Nigeria has quite a few taboos, some seem a bit silly where as others are quite practical. Some of these taboos are more traditional, but the majority come from exposure to the modern world.
Traditional Taboos:
Men's Herds: In Nigeria, it is considered very rude to ask a man how big his herd is, especially in Nigeria's Yoruba society.
Yams: In the month of August, it is forbidden to eat yams or sweet potatoes. This taboo mainly applies to the Igbo tribe in Nigeria.
Left Hands: In the Urhobo tribe, it is considered a taboo to use your left hand frequently, especially to eat. It can be considered an insult to some people, and is also considered unclean. It is preferable that you use your right hand to complete actions, however, you may use both of your hands if you find that difficult.
Chopping Fire Wood at Night: It is considered bad for a man to chop fire wood at night, mainly because of a superstition that the Nigerian people have. It is believed that if you chop firewood at night, you will turn into a statue.
Killing Monkeys: In Idemilli, it is considered both a taboo, and a crime to kill a monkey. The killing of snakes is also forbidden.
Greetings: It is considered a major taboo to introduce yourself to someone without inquiring about their well-being first.
Modern Taboos: Gay/Transgender: In Nigeria, it is considered a major offense to either be in or support the LGBTQ+ community. These actions are punishable by jail, and in some tribes, death.
Suicide: Although always a taboo, committing suicide has now become a crime, and when it is committed, the whole family is punished and must pay extensive fines.
Religion: It is considered very rude for visitors or tourists to make generalizations about Nigeria's religion, as it is an extremely diverse country that has many different traditions and tribes.
Traditional Nigerian Clothes: Tourists who wear traditional Nigerian clothes are frowned upon, as Natives find those kinds of actions stupid and insulting. Although Nigerian clothes are beautiful, it is best to refrain from wearing them if you are not a native of Nigeria.
